yeah.. so to fasten the covers and ensure that next time it does not fail.. do we have any calculations, that by passing the short circuit current of 22kA through breaker, energy released can be calculated and based on energy, pressure can be calculated.
Test has been conducted on enclosure along with breakers.
Breaker are rated for 240vAc 200A 22kA
Enclosure is rated for 3R.
Short circuit test is conducted for 22KA for 0.1 sec. Arc generated in breaker compartment… breaker tripped but still arc generated inside breaker compartment.
Covers...
When Low Voltage MCCB say 200A 22kA 240AC is tested for short circuit test can anyone provide below information
1. How to calculate internal pressure generated in an enclosure
2. how to calculate energy released during test and how to co-relate it with pressure generated.
